Rework of Leadless Devices Course

The popularity of leadless devices such as QFNs, LGAs and LCC has grown trendmendously over the last few years. Due to excellent heat dissipation, overall end device sizes have shrunk (particularly in the handheld device area). Unfortunately, the cost of rework per component has increased substantially for these device types as their very small size have made rework difficult. For those companies that want to have the capability of reworking small, lead free or tin-lead leadless devices, BEST offers the Leadless Device Rework Certification.

The leadless device rework course is comprehensive and employs the skills necessary to perform rework of electronic printed circuit boards that include QFN, LGA, LCC and other leadless device technologies. During the course, the student will be introduced to component identification, terms and definitions, re-bumping techniques, pasting, placing and reflowing, and hands-on soldering/desoldering techniques utilizing state-of-the-art workstations. This course is structured to be in accordance with IPC-A-610, IPC-7711 and IPC-7721.
